Resource center

CGI has helped California modernize its tax systems through the Enterprise-Data-to-Revenue (EDR) project, generating more than $2.8 billion in additional revenue to date. A common view of information for government and taxpayers also increases transparency and citizen service.

The Kentucky Department of Revenue (DOR) partnered with CGI to upgrade to the newest version of its award-winning Computer Assisted Collection System for Government (CACS®-G) to improve taxpayer service and increase collections.
